41. Jump to a Function Within a Buffer.

Suppose you have a file with a lot of functions in it. Well, this package
makes it easy to jump to any of those functions. The names of the functions
in the current buffer are automatically put into a menubar menu, you select
one of the function-names and the point is moved to that very function. The
mark is pushed on the mark-ring, so you can easily go back to where you
were. Alternatively, you can use enter the name of the desired function via
the minibuffer which offers completing read input. In addition, the name of
the function before point is optionally displayed in the modeline.
